Title: Method and apparatus for breaking up rock containing liquid or gaseous hydrocarbons
IPC: E21B4/00
Filed: 1971-04-26
Abstract: 1342954 Wells &c COMPAGNIE FRANCAISE DES PETROLES 26 April 1971 [15 May 1970] 11287/71 Heading E1F A well 1 is fractured by forming a hole 11 at an angle to the well; placing an explosive charge in the bottom of the hole 11 and exploding the charge. A tool holder comprising a tube 13 having holes 16 is anchored in the well by shoes 19, and a drilling tool having a body 17 is lowered into the holder, an indexing device 20 ensuring that the outlet of a rigid tube 29a, 29b in the tool is opposite one of the holes 16. In the tool an electric motor 22 rotates shafts 23, 24, the shaft 24 being moved longitudinally for feeding a bit 31 by a piston 25. A flexible shaft 28 carrying the bit is connected to the shaft 24 and guided by the tube 29a, 29b to drill a hole 11. A pump 34 draws fluid from the well to cool the motor and to enter the tube 29a, 29b to act as drilling fluid, drillings falling into a basket 36. After a hole 11 has been drilled the drilling tool is raised and lowered into the holder to drill another hole. A finger 51 stops drilling and may be set to interrupt the drilling of a hole so that the end of a hole may be sampled by a core drill. After the holes have been drilled the drilling tool is removed from the well, and a tool 37 for setting the explosive charges is lowered into the holder. A tool motor 38 is rotated to drive a piston and cylinder 41, 42 downwardly, rigid tubes 45 supported by the cylinder forcing depending flexible tubes 46 through guide tubes 47 to enter the holes. The tubes 46 contain the explosive charges and glass balls. Before the tubes 46 extend to the bottoms of the holes movement of the cylinder is stopped and the piston expels liquid 50 (which may be explosive) from the cylinder to project the charges into the holes. The anchor and setting tool are withdrawn and the charges are exploded from the surface or by a delayed action device.

Abstract: 542,365. Hydraulic presses &c. JACKSON, C. E., and HUNT, T. J. July 6, 1940, No. 11328. [Class 69 (ii)] In a press or like machine, the movable ram 11 is actuated hydraulically by means of a piston 14 working in a cylinder 13 of relatively large diameter into which liquid is forced from a single stroke pump 18 of smaller diameter, the pump piston 19 being mechanically actuated through a brake-controlled differential gearing 25 from a source of power such as an electric motor. The piston 19 is secured to a rack 20 meshing with a pinion 21 on a shaft 22 to which is keyed a gear wheel 23 meshing with a pinion 24 driven through the bevel differential gearing 25 from a pulley 26. The gear 25 is of the kind described in Specification 388,165, [Group XXIV], the side gear remote from the pulley being mounted on a shaft carrying a brake drum which co-operates with a band brake controlled by a pedal 30, whilst the planet pinions are rotatable on a crossshaft in a casing carrying the pinion 24. The lower end of the rack 20 is attached to a piston 32 working in a dash pot cylinder 33 the lower air compartment of which is fitted with a small passage 34 the area of which is adjustable by a screwed valve 35. Any loss of operating liquid due to leakage &c. is automatically made up from a reservoir 36 through a non-return valve 37.

The polymerization products may be used in the form of plastic films or spread on the glass sheets in powder form and subsequently fused, or poured while hot on to heated glass sheets. Air bubbles are removed from the compound glass assembly and adhesion effected by applying pressure first at the centre and gradually extending the pressure towards the edges. Specification 313,569, [Class 22, Cements &c.], is referred to. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the use of a product obtained by polymerization of vinyl compounds with one another or with other compounds capable of polymerization. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,273,673. Jet engine air intakes. W. DETTMERING. March 10, 1970 [March 14, 1969], No. 11490/70. Headings F1G and F1J. In a jet engine designed for use at hypersonic velocity, a rotating non-power driven bladed rotor is disposed at the inlet of the air intake duct and causes the hypersonic air-flow to be decelerated to a lower but still supersonic velicity. In Fig. 1 the bladed rotor 4, 4<SP>1</SP> is disposed at the inlet of the air intake duct 3 and rotates about the axis 5. A conical body 1 is disposed upstream of the rotor. In a second embodiment the bladed rotor 4 is arranged to drive an auxiliary power means, and a row of stationary guide vanes is disposed downstream of the rotor blade assembly. The bladed rotor may be arranged to drive the first stage of an axialflow compressor of the engine. The intake rotor may be connected to a turbine disposed downstream of the combustion chamber of the engine so as to assist the drive thereof. In a further embodiment the intake rotor is connected to the compressor and turbine assembly. At hypersonic velocities the turbine is by-passed and air flows into the intake through the bladed rotor. At lower velocities the bladed rotor in the intake is by-passed and the by-pass duct around the turbine is closed.

Title: Improvements in or relating to combined kinematographic and sound record films
IPC: G11B7/00
Filed: 1930-04-11
Abstract: 345,524. Photo-electric cells. KODAK, Ltd., Kingsway, London.- (Assignees of Jones, L. A. ; Kodak Park, Rochester, New York, U.S.A.) April 11, 1930, No. 11509. Convention date, April 12, 1929. [Class 39 (i).] Relates to kinematograph films of the kind comprising a number of differently coloured sections, each section being uniformly tinted and carrying both a picture and a sound record. According to the invention, undue diminution of the sound-producing radiations caused by the density of the tinted support, or undesirable volume changes in passing from one section to another having a different colour, is prevented by employing a series of colouring materials or dyes for tinting the sections which transmit radiations in different portions of the visible spectrum to different degrees, but which transmit to the same degree radiations in that portion of the spectrum in which the light sensitive cell is most efficient. Characteristic curves appear in the Specification to show how photo-electric cells of potassium, Fig. 2, and caesium, Fig. 2c, respond to light in various parts of the spectrum, and a series of tints as shown in Fig. 9 are chosen the density curves of which (see for example the curve for yellow shown in Fig. 4) are seen to have the same low value for wave-lengths of the order of 400 m.Á and 700 m.Á at which the potassium and caesium cells respectively are most sensitive.

Patent GB-804237-A (GB)
Title: New indole derivative and process for its preparation
Filed: 1957-04-10
Abstract: The invention comprises 5-hydroxy-isotryptophane, and a process for its preparation by reducing a 5-benzyloxy-indole-2-carboxylic acid dialkylamide with a mixed metal hydride, quaternizing the dialkylamine so formed with an alkyl halide having 1 to 6 carbon atoms or a dialkyl sulphate whose alkyl groups have 1 or 2 carbon atoms and reacting the quaternary ammonium compound with an acylaminomalonic acid dialkyl ester in the presence of a sodium alcoholate, partially hydrolysing the 5-benzyloxy - a  - acylamino - a  - carbalkoxy-indole-(2)-propionic acid alkyl ester obtained while retaining the acylamino group, then decarboxylating the acid liberated and treating the decarboxylation product, in any order desired, with sufficient hydrolysing agent to split the acylamino group and an alkyl ester group if still present, and with one mol. of catalytically activated hydrogen.  In an example, 5-benzyloxy-indole-2-carboxylic acid chloride (from the acid and thionyl chloride) is condensed in benzene with dimethylamine, and the resulting 5-benzyloxy-indole-2-carboxylic acid dimethylamide reduced with lithium aluminium hydride in tetrahydrofuran.  The 2-dimethylaminomethyl-5-benzyloxy-indole so formed is quaternized with methyl iodide and the methiodide condensed with formylaminomalonic acid ethyl ester in the presence of ethanolic sodium ethoxide; spontaneous partial hydrolysis and decarboxylation occur, yielding 5-benzyloxy-a -formylamino-indole-(2)-propionic acid ethyl ester which on heating with aqueous sodium hydroxide followed by hydrogenolysis over palladium charcoal yields 5-hydroxy-isotryptophane.
